What are the stages of sleep?
Sleep has been traditionally divided into 4 categories: awake, light, deep, and REM sleep. Each one plays an essential role in maintaining your mental and physical health. Note: As you’re reading about sleep, you may also see the terms “NREM” or “Stages 1-4.” These are simply other terms for the phases of sleep.
What happens during NREM?
Non-REM (NREM) sleep
It involves light sleep from which you can be awakened easily. Stage N2 lasts from about 30 to 60 minutes. During this stage, your muscles become more relaxed and you may begin to have slow-wave (delta) brain activity. Stage N3 is deep sleep and lasts about 20 to 40 minutes.
What happens during Stage 1 NREM sleep quizlet?
Sleep stage characterized by rapid eye movements and increased dreaming. … In this stage, and individual’s eye roll slowly, muscles relax and heart and breathing rate decreases. Theta Waves. Occurs during stage 1 NREM sleep, characterized by medium frequency brainwaves with mixed amplitudes.
What happens in Stage 1 of sleep?
Stage 1 is essentially the “dozing off” stage, and it normally lasts just one to five minutes. During N1 sleep, the body hasn’t fully relaxed, though the body and brain activities start to slow with periods of brief movements (twitches).
What is stage1 sleep quizlet?
Stage 1. Transition from waking to sleeping; irregular waves with occasional alpha waves. Stage 2. Transition from lighter to deeper sleep; sleep spindles (waves with alternating periods of calm and flashes of intense activity) appear.
What occurs physiologically during REM sleep quizlet?
REM sleep is called paradoxical sleep – internally the brain and body are active while externally the body appears calm and inactive. Most dreaming occurs during REM sleep.
What term do sleep researchers use to designate stages 1 to 4 of sleep?
As you sleep, your brain cycles through four stages of sleep. Stages 1 to 3 are what’s considered non-rapid eye movement (NREM) sleep, also known as quiet sleep. Stage 4 is rapid eye movement (REM) sleep, also known as active sleep or paradoxical sleep.
What wave is characteristic of stage 1 sleep?
Which brain wave patterns occur during sleep stages 1 through 4 quizlet?
Stages 1-4 are also known as NREM or non-REM sleep. During stage 1 sleep, the brain is dominated by theta waves. The sleeper is in a very light sleep with closed eyes, but the sleep is very light and it is easy to be woken up. Indeed, sometimes a person wakes up with a start in a phenomenon called a hypnic jerk.
Which of the following occurs during REM sleep?
Which of the following occurs during rapid eye movement (REM) sleep? The muscles are paralyzed, and body temperature, blood pressure, and heart rate and respiratory rate increase.
Which of the following occurs in the first stage of sleep quizlet?
Stage 1 is light sleep where you drift in and out of sleep and can be awakened easily. In this stage, the eyes move slowly and muscle activity slows. During this stage, many people experience sudden muscle contractions preceded by a sensation of falling.
